Current Status - last updated February 11, 2020

✅ Under Consideration
❌ Not Prioritized
❌ Not Under Active Development
ℹ️ Cypress currently supports Firefox and Chrome-family browsers (including Edge and Electron).

Objective

Add support for running Cypress tests within the IE 11 web browser.

IE 11 End of Life
According to Microsoft, development of new features for Internet Explorer has ceased. However, it will continue to be maintained as part of the support policy for the versions of Windows with which it is included.

This is a placeholder proposal issue. Necessary details will be added once this feature is prioritized.

As someone who works on an application for the healthcare sector where IE 11 will be around a long time I would love to see support implemented. Kudos for considering this rather then just dropping plans because MS declared IE 11 EOL. :)

There is still a massive amount of computers on IE 11 and while IT departments exist this will probably remain the case, so this would be very good to have.

Hope Safari will get higher priority as it definitely not going to disappear and actually is new IE 😁

[jpike88]

@levenleven thats weird cause I never have Safari behaviour deviate from Chrome. shouldn’t IE11 be more important because of the much higher risk of deviation (such as use of polyfills)?

[levenleven]

@jpike88 jokes aside, both are important. I'm just hoping MS will try to kill IE faster because Edge should have compatability mode. Also more and more non enterprise projects just drop IE support

There's already an issue for this: #1564
It has—as of today—96 👍 and a 15$ bounty; #6423 should be closed as a dupe of #1564.
Also remember to update the closing comment on #310.

We actually been using Cypress for more than a year and waiting for IE11 support, because we have a lot of customers in Japan, who are using IE11. Those clients are very important to us. So if Cypress doesn't plan to support IE11, we will have to switch to some other framework.
